No. The process does not violate the law of conservation of energy.
- When the body falls from a height, its potential energy changes into kinetic energy progressively.
- A decrease in the potential energy is equal to an increase in the kinetic energy of the body.
- During the process, the total mechanical energy of the body remains conserved.
- Therefore, the law of conservation of energy is not violated.
Law of conservation of energy
The Law of Conservation of Energy refers to an isolated system in which there is no net change in energy and where energy is neither created nor destroyed. Although there is no change in energy, energy can change forms. Thus, for a freely falling object, its potential energy decreases but kinetic energy increases in such a way that its total mechanical energy remains constant. Moreover, the potential energy of a freely falling object is converted into its kinetic energy.
